I made this view of an empty Bord na Mona train crossing the bog on its way to reload.

The trick making this photo work was to expose for the sky while letting the train go relatively dark. I was working with Ilford HP5 black & white film, and during processing, I used two developers followed by selenium toning of the negatives to extract the maximum shadow detail.

My intent was a moody and stark view of the train against the textured sky.
